Applied Machine Learning Coding in R | CARET package | QDA in R | IRIS Dataset


R is a programming language that is widely used for data analysis and statistical computing. It has a large ecosystem of libraries and packages that provide a wide range of machine learning algorithms and tools.

One of these packages is called CARET (Classification and Regression Training) package, which provides a unified interface for a wide range of machine learning models including QDA (Quadratic discriminant analysis).

Quadratic discriminant analysis (QDA) is a statistical method that is used for classification problems. It works by fitting a Gaussian density to each class and then assigns a new observation to the class with the highest posterior probability.

In this example, we will be using the IRIS dataset, which contains information about different variations of the IRIS flower, such as the setosa, virginica, and versicolor. We will use the CARET package in R to build a QDA model and classify the IRIS flowers using this model.

First, we will preprocess the IRIS data and split it into training and testing sets. Next, we will use the CARET package to train the QDA model on the training data. We will then use the model to predict the class of each flower in the testing data.

In summary, Applied Machine Learning Coding in R using CARET package and QDA (Quadratic discriminant analysis) in R using IRIS dataset is a powerful combination of a programming language, package and techniques that can be used to classify the IRIS flowers. CARET package provides a unified interface for a wide range of machine learning models and QDA is used to classify the IRIS flowers based on their characteristics.


In this Applied Machine Learning & Data Science Recipe (Jupyter Notebook), the reader will find the practical use of applied machine learning and data science in Python programming: QDA in R.
